What is the ECU?
An engine control unit (ECU) is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance.
What is engine remapping?
Cardinal Motors Engine remapping specialise in altering or replacing the software in a car’s ECU, changing how it performs and potentially removing any restrictions on its potential. The old way of doing it involved swapping a circuit board or chip inside the ECU, but nowadays the new software is often installed via your car’s diagnostic port via a laptop or a handset provided by Cardinal Motors
The engine control unit (ECU) is basically a computer that controls how the engine works, a bit like a brain.
But the default settings – or maps – are not necessarily the best they could be, as manufacturers who sell their cars around the world have to take into account different climates, fuel qualities and laws when they program the software.
Car makers are also known deliberately to limit the performance of their cars through the ECU so they can release faster models at a later date, with just a few software changes and a much higher price tag.
